Forking claw-code: containment, observability, and why
- 01 April 2026
When claw-code leaked and hit 50K stars in two hours, I did what any curious engineer would do: I cloned it. And then I did what any paranoid engineer would do: I refused to run it on my host.
The project is a reconstructed harness [1] for agentic coding assistants. It is impressive work, and I wanted to understand how it ticked. But running someone else’s agent runtime with full tool access on your machine, reading your files, executing shell commands, making network requests, that requires a level of trust I was not ready to extend. Not because I suspected malice, but because I could not verify the absence of it. I needed containment first, observability second, and only then would I start experimenting.
Reducing my cognitive load on food
- 29 March 2026
A typical day leaves very little room for improvisation. Sleep, work, basic maintenance, the small rituals that keep a life running. They fill almost the entire 24‑hour cycle. When I looked closely at where my time was going, food turned out to be the largest flexible block. Not the eating itself, but everything around it: deciding what to make, checking what I have, preparing it, cleaning up afterward. It was a constant background process that consumed more time and attention than I wanted to give it.
I enjoy eating, and I want the food I eat to be nutritious and unprocessed [1]. But preparing that kind of food every single day takes time I don’t always have. Meal prepping became a way to reclaim that time without compromising on what I value. I’ve been doing so for almost a year now. It gives me predictable meals, predictable nutrition, and predictable effort. It removes the daily decision‑making and replaces it with a weekly session that stabilizes the rest of the week.
Seasonal Twilight
- 28 March 2026
I went on another hike today, up the Altkönig in the Taunus.
Down in the valley, the weather was wet, and grey. Exactly what I expected for the spring season to be at the start of April.
Why my heart rate is on the internet
- 27 March 2026
I built an ETL pipeline [1] for my personal health data. It updates every ten minutes and feeds a data warehouse [2]. And then I made it public… which might confuse you. It looks like a quantified‑self stunt [3] or some kind of cry for help, but it isn’t. It’s a privacy experiment, and the origin of it is much more mundane than it appears. It started with an unhealthy relationship with optimization.
A few years ago, I wanted to “improve” my body. Nothing dramatic, just a few centimeters here and there. I’m naturally skinny, so I focused on recomposition. I tried a ketogenic diet because some of the claims around it were interesting. I started counting calories and macros. The diet failed and I stopped, but the counting didn’t. At some point, calorie counting stopped being a tool and became a background process… a tab I couldn’t close.
Film Noir AI Video Generation
- 24 March 2026
I love film noir… The hard shadows, the moral ambiguity, the way everything feels like it’s one cigarette away from collapsing. No grand resolution, everybody loses. It just resonates with me on a level that no other genre of movie ever has.
Naturally, when I started experimenting with Grok Imagine for AI video generation, noir was the first aesthetic I tried to push it into.
NVIDIA Tesla V100 Proxmox Guest VM Pass-Through
- 07 February 2026
By default, the Proxmox host will claim the GPU, as you can see by a kernel
driver nouveau being active.
We now have to blacklist the CPU from being used by proxmox itself, so that it can be passed-through to my virtual host.
Why Infrastructure Architecture Is Entering Its Agentic Era
- 04 February 2026
For a long time I assumed that cloud architecture would remain one of the last areas of engineering that resisted automation. Writing code could be delegated. Testing could be delegated. Even parts of design could be delegated. But architecture felt different. It required context, judgment, and the ability to understand how many moving parts fit together. It felt like a space where humans would always have the upper hand.
That belief has been fading quickly.
Learning Content as Code

Building a Libre Open-Source e-Learning Authoring Toolchain
Most people have taken an online course at some point, maybe a workplace training, a coding bootcamp, or a university module. Behind the scenes, those courses are usually built with specialized software platforms. They often come with drag‑and‑drop editors, proprietary formats, and limited ways to move your content elsewhere. If you switch platforms, you often have to rebuild everything from scratch.
Winter Chills
- 01 December 2025
Leaf-like frost designs shimmered on my windowpane, illuminated by the hush of winter night.
